Description

Method for calculational approximation of a priory coefficients specifying neutron flux densities distribution relation on the reactor external shell with average height power distribution depending on position of control organs is considered. Possibility of coefficient distribution by coarse-grid programs for core physical calculations is shown. Coefficient time dependence is investigated and method for approximating multidimensional dependence of these coefficients in form of unidimensional superposition is proposed
